The invention relates to a thermal management control method for an electric vehicle, which comprises a heat source component system, a thermal management control unit and a heat dissipation system, and the heat source component system comprises each component needing heat dissipation on the vehicle and a sensor for collecting the temperature of the corresponding component needing heat dissipation in real time; each sensor collects the temperature of the corresponding part needing heat dissipation in real time and transmits the temperature to the heat management control unit. When the temperature of any part needing heat dissipation is higher than a preset starting temperature value, the heat dissipation system is controlled to be started and output at the initial set output power; the output power of the heat dissipation system is further judged and adjusted according to the real-time temperature information, and when the maximum value of the temperature change rate of any part needing heat dissipation is a positive value, the output power of the heat dissipation system is improved; when the maximum value of the temperature change rate of each part needing heat dissipation is a negative value, the output power of the heat dissipation system is reduced; and when the temperature of each part needing heat dissipation is lower than the preset starting temperature value, the heat dissipation system is closed. The heat dissipation system can be quickly regulated and controlled to work, and the heat dissipation effect is improved.
